应用案例 1：
 
  欧盟委员会联合研究中心通过无人机遥测技术研究叶缘焦枯病菌在橄榄树中的感染。同时通过FluorPen叶绿素荧光仪和RP400光谱仪直接检测叶片的叶绿素荧光和反射光谱植被指数，用于对照修正无人机遥测数据。研究结果发表在《Nature Plants》（Zarco-Tejada，2018）。
 
应用案例 2：
  水稻灌浆期的夜间高温会显著影响水稻的产量。捷克科学院全球变化研究中心与国际水稻研究所合作研究夜间高温对成熟水稻穗光学特性的变化追踪。研究者使用FluorPen手持式叶绿素荧光仪测量了光合系统有效光化学效率ΦII（也称为有效量子产额QY或ΦPSII）和稳态荧光Fs。同时使用PolyPen手持式植物反射光谱测量仪的前期型号WinePen测量了反射光谱曲线，并计算了PRI、mSR705、mND705、R470/R570、R520/R675等9项植被指数。这些植被指数与水稻叶片/穗的光合能力、稳态荧光、叶绿素浓度等紧密相关（Gil-Ortiz R et al. 2020）。
